Based on a simultaneous-equation model consisting of aggregate demand and short-run aggregate supply, this paper estimates a reduced-form equation specifying that the equilibrium real GDP is a function of the real effective exchange rate, the government deficit as a percent of GDP, the real interest rate, foreign income, labor productivity, the real oil price, the expected inflation rate, and the interactive and intercept binary variables accounting for a potential change in the slope of the real effective exchange rate and shift in the intercept. Applying the exponential GARCH technique, it finds that aggregate output in Australia has a positive relationship with the real effective exchange rate during 2003.Q3 - 2013.Q2, the government deficit as a percent of GDP, U.S. real GDP, labor productivity and the real oil price and a negative relationship with the real effective exchange rate during 2013.Q3 - 2016.Q1, the real lending rate and the expected inflation rate. These results suggest that real appreciation was expansionary before 2013.Q3 whereas real depreciation was expansionary after 2013.Q2 and that more government deficit as a percent of GDP would be helpful to stimulate the economy. Hence, the impact of real appreciation or real depreciation on real GDP may change overtime.

본 연구는 최근 글로벌 외환시장에서 첨예하게 대립하고 있는 환율갈등의 요인을 분석하기 위해 국가간 실질 및 명목이자율 차이가 환율결정에 미치는 영향을 분석하였다. 유위험, 무위험, 및 실질이자율평가의 실증분석 결과를 종합해 보면 유위험이자율평가가 다른 두 경우보다, 실질이자율평가가 무위험이자율평가 보다 환율결정에 더욱 영향을 미치기는 하지만 그 정도는 충분히 크지 않은 것으로 분석되었다. 또한, 국가간 환율결정에 실질이자율평가가 성립되지 못하는 원인을 규명하기 위해 국가할증, 환율변동위험 할증, 및 통화할증을 분석하였는데, 그 결과에 의하면 국가할증과 환율변동위험 할증이 실질이자율평가의 성립을 어렵게 하는 요인으로 분석되었다. 실증분석 결과를 종합해 볼 때 최근의 국가간 환율갈등의 원인은 외환위기 이후 글로벌 외환시장에서 환율이 각국의 경제력을 바탕으로 결정되기 보다는 시장의 외부요인인 전략에 의해 영향을 받았기 때문인 것으로 보인다. 따라서 환율갈등을 완화 또는 근본적으로 해결하기 위해서는 각국의 외환정책 당국은 시장지향적이고 시장결정적인 환율제도를 구축하여야 할 것이다.

The study aims to examine the impact of productivity in addition to the policy of increasing the foreign investors' ownership rate on the performance of businesses which were listed on Vietnam's stock exchange market from 2010 to 2017. With the database of 3.961 observations, the study employs a statistical method - multiple regression to estimate the relationship between labor productivity, foreign ownership as well as other firm-level characteristics and firm performance. Research findings show that increasing labor productivity and increasing foreign ownership rates help increase firm performance. In addition, except for financial leverage, variables such as liquidity and firm size have positive effects on firm performance measured by Tobin's Q. These findings have theoretical contributions and practical implications for managers, investors and government in Vietnam. Managers should pay attention to improving labor productivity through employing incentive mechanisms, building a good working environment, investing in technology, etc. in order to enhance the firm performance. Investors could utilize the labor productivity and foreign ownership indicators to select stocks of good companies for investment. For Vietnamese government, relaxing the limit of foreign ownership and accelerating the divesting of State capital in State-owned enterprises could help increase the investment scale of foreign investors and resulting in positive effects on the firm performance.

Purpose - This article analyzes the impact of macroeconomic variables of the United States, China, and Korea on KOSPI and VKOSPI, in that United States and China have a great influence on Korea, having an export-driven economy. Design/methodology/approach - The influence of US, China, and Korea interest rates, industrial production index, consumer price index, US employment index, Chinese real estate index, and Korea's foreign exchange reserves on KOSPI and VKOSPI is analyzed on monthly basis from Jan 2012 to Aug 2023, using multifactor model. Findings - The KOSPI showed a positive relationship with the U.S. industrial production index and Korea's foreign exchange reserves, and a negative relationship with the U.S. employment index and Chinese real estate index. The VKOSPI showed a positive relationship with the Chinese consumer price index, and a negative relationship with the U.S. interest rates, and Korean foreign exchange reserves. Next, dividing the analysis into two periods with the Covid crisis and the analysis by country, the impact of US macroeconomic variables on KOSPI was greater than Chinese ones and the impact of Chinese macroeconomic variables on VKOSPI was greater than US ones. The result of the forward predictive failure test confirmed that it was appropriate to divide the period into two periods with economic event, the Covid Crisis. After the Covid crisis, the impact of macroeconomic variables on KOSPI and VKOSPI increased. This reflects the financial market co-movements due to governments' policy coordination and central bank liquidity supply to overcome the crisis in the pandemic situation. Research implications or Originality - This study is meaningful in that it analyzed the effects of macroeconomic variables on KOSPI and VKOSPI simultaneously. In addition, the leverage effect can also be confirmed through the relationship between macroeconomic variables and KOSPI and VKOSPI. This article examined the fundamental changes in the Korean and global financial markets following the shock of Corona by applying this research model before and after Covid crisis.

본고(本稿)는 원화환율(貨換率)의 적정운용(適正運用)을 모색해 보았다. 이를 위해 먼저 Lipschitz(1980)의 방식을 따라 원화(貨)의 실질실효환율(實質實效換率)을 안정시킬 수 있는 적정통화(適正通貨)"바스켓"을 구성해 보았다. 80년대 중반 이후 이를 적용했을 경우 실제의 경우보다 원화(貨)의 실질실효환율(實質實效換率)이 훨씬 안정될 수 있었음이 입증되었다. 또한 특정시점에서 구한 적정가중치(適正加重値)를 계속해서 적용하는 것보다 주요환율(主要換率)과 상대물가간(相對物價間)의 관계변화(關係變化)에 따라 가중치(加重値)를 수정해 나가는 것이 바람직하다는 점도 지적되었다. 이와 같은 적정통화(適正通貨)"바스켓"과 그에 기초한 "바스켓"환율(換率)은 우리의 경상수지(經常收支)나 생산성(生産性) 변화추이(變化推移)와 함께 시장평균환율제도하(市場平均換率制度下)에서 적절한 환율운용(換率運用)을 위한 중장기적(中長期的) 지표(指標)의 하나가 될 수 있을 것이다.

In this paper, the unbiasedness hypothesis cannot be rejected for JPY. It means that Japanese forward exchange market is efficient. This implies that there would not be an unusual profit from speculation. However, the unbiasedness hypothesis can be rejected for THB, HKD, IDR. It means that Asian forward exchange market is inefficient. This implies that there would be an unusual profit from all available information. This suggests that forward exchange rates cannot be an unbiased estimator of future spot exchange rate. This result explains that the actual pricing for forward rate is not based on the international financial market's pricing mechanism of interest rate parity theory, but rather depends upon that simple market expectations and aspirations.

본 연구에서는 국내 코스피 및 코스닥의 비금융 상장사를 대상으로 2000년부터 2008년까지 분기별 현금흐름에 반영된 달러화, 유로화, 엔화, 위안화 등 주요 외국통화의 단기 환노출을 측정하여 보았다. 현금흐름을 사용할 경우 환율변동이 미치는 단기적인 영향(단기노출)을 장기적인 영향과 분리하여 측정할 수 있다는 장점을 가진다. 기업의 환헷지는 환율변동이 가져오는 장단기 영향에 대해 차별적인 효과를 미친다는 점을 고려하면 현금흐름으로 측정된 환노출은 기업의 헷지전략에 유용한 정보를 제공한다. 분석 결과, 국내 비금융 상장사는 개별 환율에 대해서는 기존의 연구와 비슷한 결과를 보였으나, 위안화를 제외한 세 개의 환율 전체에 대해서는 30%를 훨씬 웃도는 단기 노출비중을 보였다. 단기 환노출은 헷지가 비교적 쉽다는 점을 고려하면 위의 결과는 국내 기업이 환위험 관리에 취약함을 나타낸다. 또한 코스닥 기업이 코스피 기업에 비해 유의적으로 더 높은 노출 수준으로 보여, 코스닥 기업의 환위험 관리가 더욱 허술함을 알 수 있다. 한편 기존의 연구와는 달리, 영업이익으로 측정된 현금흐름의 환노출 부호는 양으로 나타나 국내 기업의 경영현실을 주가보다는 단기 현금흐름이 더욱 잘 반영하였다. 또한 위안화를 제외한 환율-기업 표본을 가지고 분석한 결과, 규모 및 부채비율은 환노출 수준에 대해 유의적인 설명력을 갖는데 반해 수출비중은 설명력이 없었다.

The study investigates the asymmetric effect of exchange rate changes on stock prices in Vietnam. We use the nonlinear autoregressive-distributed lag (ARDL) analysis for monthly data from 2001:01 to 2018:05, based on VN-Index stock price collected from Ho Chi Minh Stock Exchange (HOSE); the nominal exchange rate is separated into currency depreciation and appreciation through a partial sum decomposition process. Asymmetry is estimated both in the long-run relationship and the short-run error correction mechanism. The research results show that the effect of exchange rate changes on stock prices is asymmetrical, both in the short run and in long run. Accordingly, the stock prices react to different levels to depreciation and appreciation. However, the currency appreciation affects a stronger transmission of stock prices when compared to the long-run currency depreciation. In the absence of asymmetry, the exchange rate only has a short-run impact on stock prices. This implies a symmetrical assumption that underestimates the impact of exchange rate changes on stock prices in Vietnam. This study points to an important implication for regulators in Vietnam. They should consider the relationship between exchange rate changes and stock prices in both the long run and the short run to manage the stock and foreign exchange market.

This paper tried to estimate the pass - through of exchange rate changes to export price of fishery products using export price function. The results are as follows : 1) The variable of fluctuation of exchange rate of Won(equation omitted) to Yen(equation omitted)(variable E2) is more powerful explanatory variable than that of Won to U.S. dollar to explain the fluctiation of export price of fishery products(varible $P_{t}$)- 2) The variable of fish catches(variable K $P_{t}$) is also found to be a statistically significant varible but that of producer price index is not found. 3) The variable E2 have statistically a more influence on variable $P_{t}$ than variable K $P_{t.}$ 4) The estimation shows us that 1% of fluctuation of variable E2 could result in 0.9978% of fluctuation of variable $P_{t.}$

Applying Ismailov and Rossi (2018), I newly construct the Korea FX uncertainty based on the density distribution of historical forecast errors. This uncertainty index properly captures the rare but significant events in the Korean currency market and provides information distinct from other uncertainty measures in recent studies. I show that 1) FX uncertainty arising from unexpected depreciation has a stronger impact on Korea-U.S. exchange rates and that 2) macro variables, such as capital flows or interest rate differentials, have predictive ability regarding Korea FX uncertainty for short horizons. These findings enable us to predict the events of sudden currency crashes and understand the Korea-U.S. exchange rate dynamics.
